Marcus, Rudolph A. (1923–)




Rudolph Marcus
Canadian-born US physical chemist who developed what is now known as the Marcus theory for electron transfer (oxidation-reduction) reactions of solvent molecules. His formula calculates the size of the energy barrier the electrons must surmount to move from one molecule to another. The theory is applicable to such processes as photosynthesis and the electrical conductivity of polymers. He was awarded the 1992 Nobel Prize in Chemistry.
